Cardiac Arrhythmias

Cardiac arrhythmias refer to abnormal heart rhythms characterized by irregularities in the speed, regularity, or sequence of the heart's electrical impulses. These irregular rhythms can manifest as too fast (tachycardia), too slow (bradycardia), or irregular beats. Arrhythmias can occur in the atria (upper chambers) or the ventricles (lower chambers) of the heart and may be caused by various factors, including heart disease, age, genetics, or certain medications. Symptoms of cardiac arrhythmias can range from palpitations, dizziness, and shortness of breath to more severe complications, such as fainting or cardiac arrest. Diagnosis often involves electrocardiograms (ECGs or EKGs), Holter monitoring, and other cardiac tests to evaluate the heart's electrical activity and identify the specific type of arrhythmia.
